As shown throughout the story “The Tell Tale Heart” by Edgar Allen Poe, the unnamed narrator remains an unreliable narrator. Exemplified through his actions and thoughts, it is quite obvious the narrator is deranged and mentally unstable, proving the point he is an insane innocent as well as an unreliable source. He feels it is necessary to murder an old man he lives with due to his one blind eye. In addition, toward the end, he envisions the old man’s dead heart pulsing and beating, driving him to insanity and admits to his crimes.
As explained, the unknown narrator is unreliable due to his lack of mental stability. The exactness with which the narrator recounts murdering the old man, as if his stealthy way of executing the crime is evidence of his sanity, reveals his monomania and paranoia. He attempts to prove his sanity by murdering an old man in his sleep due to his blind eye, but resists and explains his thoughts to the reader as “but I found the eye always closed; and so it was impossible to do the work; for it was not the old man who vexed me, but his Evil Eye. (Edgar Allen Poe 1). This further proves that his mental state is crumbling for he sees the old man and the “Evil Eye” as two different beings. However, he ends up killing the old man to rid himself of the eye as well, giving more evidence he is unreliable and insane. Further evidence that the unnamed narrator lacks sanity is that after committing the crime of homicide and the police arrive, he is convinced that the now dead old man’s heart is still beating.
His guilt takes on the form of a hallucination to the point where he is convinced even the policemen can hear it and suspect him as a murderer. In the end, his guilt drives him to cry out and tell the police to tear up the floorboards to reveal the corpse of the old man he murdered and then dismembered. The story is driven not by his insistence upon his innocence but by insistence on his sanity and to prove that only a sane man could possibly think of this scheme. He is completely convinced that his “insanity” is in fact only a disease that sharpens his senses and made his hearing “acute”.
It is almost certain the unidentified narrator is mad, unreliable and is a victim of extreme paranoia. As exemplified through the narrator’s thoughts and perspective, he is completely unreliable for he thinks the cunning idea and execution of the plan proves his sanity and that his is murdering the “Evil Eye” and not the old man for “I loved to old man. ” (Edgar Allen Poe 1). The narrator remains unreliable and is a victim of insane innocent due to his paranoia and insistence to prove his sanity.
